A Republican US senator is calling on President Donald Trump’s administration to encourage American technology companies to develop open-weight AI models, adding a new voice to a growing debate over how the United States should approach the technology.
Senator Jim Banks, a member of the Senate Armed Services Committee, requested this in a letter released Friday (August 14, 2026). He urged the administration to consider incentives for US companies developing open-weight models while reducing American dependence on similar systems developed in China.
Open-weight models make key components publicly accessible, allowing users and developers to download them and adapt them for specific applications. They can also offer a lower-cost alternative for businesses that do not want to rely entirely on proprietary AI services.
Examples include models developed by Meta, NVIDIA and Thinking Machines. By comparison, companies such as OpenAI, Anthropic and Google operate prominent closed-weight systems, where the companies retain greater control over the underlying technology.
Banks argued that the US needs to strengthen its position in this part of the technology market as Chinese open-weight models gain popularity among American users and developers.
The senator's proposal is also linked to national security concerns. Banks asked the administration to explore measures to limit US reliance on Chinese-made open models and to make it more difficult for Chinese companies to use American semiconductor technology to develop their systems.
His comments reflect concerns in Washington that China's growing presence in OpenAI could give its technology companies greater global influence.
However, the issue has divided the US technology industry. In July, NVIDIA and Meta, along with several other technology companies and venture capital firms, urged policymakers not to impose restrictions on open-weight models. They argue that keeping the technology broadly available could benefit innovation and the wider US technology ecosystem.
"America cannot afford to see Chinese open models proliferate and burrow into the global economy only to be weaponized, like rare earths, at a time and place of China’s choosing," Banks wrote in a letter to Trump's economic adviser Christopher Phelan.
Anthropic CEO Dario Amodei, meanwhile, has raised concerns about the security implications of open-weight systems, noting that their use can be harder to monitor.

The disagreement highlights a larger question for the Trump administration: whether the US should promote open AI development as a strategic advantage or impose tighter controls because of potential security risks.
For American technology companies, the policy direction could influence future investment, access to computing hardware, and the development of AI models that can be distributed more broadly.
Banks' proposal adds political pressure to an already divided industry as Washington considers how to maintain US leadership while responding to China's expanding role in the global AI race.
